Valve Lifters and Guides Cleaning and Inspection

^ Tools Required
- J 26900-2 Micrometer





1. Use a caliper gage to measure the lifter bore diameter of the cylinder head.
Lifter Bore Diameter 31.000 - 31.025 mm (1.2205 - 1.2215 inch)





2. Use a J 26900-2 and measure the lifter diameter.
Lifter Diameter 30.966 - 30.976 mm (1.2191 - 1.2195 inch)
3. Subtract the lifter diameter measurement from the lifter bore diameter measurement to determine the oil clearance.
^ Standard Oil Clearance 0.024 - 0.059 mm (0.0009 - 0.0023 inch)
^ Maximum Oil Clearance 0.079 mm (0.0031 inch)
4. If the oil clearance is greater than the maximum, replace the lifter. If the proper oil clearance is still greater than the maximum allowed, replace the cylinder head.
